How DNA makes a difference in the criminal justice system

  • Since 1989, there have been tens of thousands of cases where prime suspects were identified and pursued—until DNA testing (prior to conviction) proved that they were wrongly accused.
  • In more than 25% of cases in a National Institute of Justice study, suspects were excluded once DNA testing was conducted during the criminal investigation (the study, conducted in 1995, included 10,060 cases where testing was performed by FBI labs).
  • An Innocence Project review of our closed cases from 2004 – June 2015 revealed that 29% of cases were closed because of lost or destroyed evidence.
